Ultrawave User Guide

Welcome

Thank you for purchasing the Source Audio Ultrawave Multiband Processor. The Ultrawave is the

first of its kind: a flexible multiband processing toolbox. Through the combination of band splitting,

exotic distortion curves, multi-band tremolo, compression, morphing, and flexible stereo processing,

the Ultrawave opens doors to a wide range of new sounds for guitar, bass, synth, and other musical

instrument applications. The Neuro Desktop and Mobile editors provide an intuitive graphical

environment to unlock the power of the Ultrawave, allowing users to create and share a growing

library of sounds.

At the core of the Ultrawave is multiband separation, distortion, and EQ. In the 1970s music

technologist Craig Anderton created a 4-band distortion tool. It was noted for lessening

intermodulation artifacts when playing complex chords, but the concept was left largely unexplored.

In 2007 Bob Chidlaw took the basics of multiband processing and added cutting-edge foldback

distortion curves, which were relatively unknown at the time. When implemented on a powerful

Analog Devices DSP chip, the Source Audio Multiwave Distortion pedal was born. The Ultrawave

starts where the Multiwave left off and leverages more than a decade of Source Audio know-how

and dramatic increases in DSP power. The Ultrawave is the ultimate expression of multiband

processing in a pedal. We hope you will enjoy our creation, and that it will provide years of

inspiration and fun.

Connecting the Pedal

Power

To power the unit, connect the included 9V DC center-negative power supply (at least 150mA

required) to the jack labeled DC 9V on the back panel.

Warning: Using a non-Source Audio supply, especially an unregulated supply, could damage the unit.

A power supply with insufficient current levels may also cause noise or other unpredictable behavior.

Please be very cautious when using 3rd-party power supplies and refer to the power supply

requirements in the Specifications section of this guide.

Connections

Guitar/Audio Connections

Using standard ¼” mono (TS) cables, connect your guitar, bass, or other instrument to the INPUT 1

jack and your amp (or the next audio device in the signal chain) to the OUTPUT 1 jack. If you have a

second amp, connect it to OUTPUT 2.

When the power and audio connections have been made, Ultrawave is ready for use.

Table of Contents Ultrawave Multiband Processor User Guide

Input Side Connections

INPUT 1

INPUT 1 is the primary input for guitar, bass, or other instruments. It can also accept line-level inputs

and will work in your amp’s effect loop. Connect it to your instrument or other audio source using a

mono (TS) 1/4” cable. Details about the appropriate signal levels are available in the Specifications

section.

INPUT 2

Use the secondary audio input for stereo sources or as the data connection to your mobile device

when using the Neuro App.

• INPUT 2 as an Audio Input: The tip contact on INPUT 2 acts as a secondary input for guitar, bass,

or other instruments. Connect your instrument (or the previous effect in the signal chain) using

a mono (TS) ¼” cable. The Ultrawave will automatically configure itself for stereo audio input.

Other routing options are available using the Neuro App. For more information about stereo

routing, refer to the Stereo Operation section.

• INPUT 2 as a Neuro App Data Input: The ring contact on INPUT 2 acts as a data connection for the

Neuro Mobile App. The Neuro App sends data to the pedal using your mobile device’s

headphone jack. Connect it to your mobile device using the included stereo (TRS) 1/8” to 1/4”

cable. It can also accept daisy-chained Neuro data from another Neuro-compatible pedal in the

chain, provided that a TRS cable is used. The audio signal (if applicable) will be on the tip contact

of the plug, and the Neuro App data will be on the ring contact. This allows audio and Neuro

data to flow on the same cable.

Table of Contents Ultrawave Multiband Processor User Guide

Output Side Connections

OUTPUT 1

This is the primary audio output. Connect it to your amplifier, recording interface, or the next device

in your effects signal chain using a mono (TS) ¼” cable.

OUTPUT 2

OUTPUT 2 can act either as an audio output or a daisy-chain data connection for the Neuro App.

• OUTPUT 2 as an Audio Output: The tip contact on OUTPUT 2 acts as the secondary audio output.

It carries an audio signal when the Ultrawave is configured with a signal routing that uses stereo

outputs. Connect it to your amplifier, recording interface, or the next device in your effects

signal chain using a mono (TS) ¼” cable.

• OUTPUT 2 as a Neuro App Data Daisy-Chain Output: The ring contact on OUTPUT 2 acts as a data

connection for the Neuro App, passing data from the Ultrawave to the next Source Audio effect

in your signal chain. You can daisy-chain the Neuro App data regardless of whether OUTPUT 2 is

configured to output audio or not. Connect OUTPUT 2 to the next device’s Neuro App Data input

(usually INPUT 2) using a stereo (TRS) 1/4” cable. The audio signal (if applicable) will be on the tip

contact of the plug, and the Neuro App data will be on the ring contact. This allows audio and

Neuro data to flow on the same cable.

Table of Contents Ultrawave Multiband Processor User Guide

Power and Control Connections

DC 9V (Power)

Connect to the included 9 Volt DC power supply. If you would like to use a 3rd-party supply, the

power supply must be regulated at 9 Volts DC (direct current), able to source at least 150 mA

(milliamps) of current, and the plug should have a center-negative polarity.

USB

Connect your computer or mobile device (Windows or Mac) to the Ultrawave’s USB port (denoted by

the icon) using a standard USB mini-B cable. The Ultrawave is a class compliant USB device, meaning

that it does not require any custom drivers. For more information about the Ultrawave’s USB

capabilities, refer to the USB Section of the User’s Guide.

CONTROL INPUT

The 3.5 mm CONTROL INPUT port connects to external control devices such as the Source Audio Tap

Tempo Switch, Source Audio Dual Expression Pedal, and the Neuro Hub. For more information, refer

to the Expression Pedal Input and Neuro Hub sections of the User’s Guide.

Controls

Note: The four top-level knob controls (Drive, Level, Sustain, and Treble) can be reassigned in the

Neuro Mobile App and Neuro Desktop Editor from a list of many possible parameters.

Footswitch

Click the footswitch to engage or bypass the pedal. Press and hold the footswitch down while the

pedal is bypassed to bank to Red LED (ALT) Mode for more presets.

Control Input / ALT Button

This small button located at the top of the pedal is used to enable or disable external control. It also

is used to control the ALT parameters on the surface of the pedal. Press and release the ALT button;

while the Control LED is flashing, turning the SUSTAIN or TREBLE knobs will access their alternate

parameters, Bass level and Mid level.

ON/OFF LED

The ON/OFF LED indicates whether the effect is bypassed or engaged. In ALT Mode, the LED

becomes red.

DRIVE Knob

Adjusts the distortion level. Turn clockwise for more distortion and saturation, or turn

counterclockwise for cleaner sounds.

Table of Contents Ultrawave Multiband Processor User Guide

LEVEL Knob

Adjusts the overall output volume. Turn clockwise for more volume, or counterclockwise for less

volume. Note: Due to the varying nature of the presets and band-splitting options, the overall

output level may change for each preset, adjusting the range of this control. Because of this, there is

no hard-set “unity gain” point on the knob.

SUSTAIN/BASS Knob

Adjusts the sustain of the distortion by manipulating the input gain before the compressor. Turn

clockwise for more sustain and a bit more saturation. Turn counterclockwise for less sustain and a

more open sound/feel.

In ALT mode, this knob controls the amount of bass frequencies present in the outgoing signal. Turn

clockwise for more low end, and turn counterclockwise for less low end.

TREBLE/MID Knob

Controls how bright or mellow the overall effect is. Turn clockwise for a more top end bite, or turn

counterclockwise for a darker sound with attenuated high frequencies.

In ALT mode, this knob controls the amount of midrange present in the distortion. Turn clockwise for

a more warm, classic sound, and turn counterclockwise for a more scooped, modern sound.

Preset Selector Toggle

Use the Ultrawave’s three-position toggle switch and two preset banks to easily access six different

presets. First Preset Bank (indicated by the green center LED): default the center toggle switch

selects between three presets stored in the first bank of presets. Second Preset Bank (indicated by

the red center LED): Pressing the ALT button on the topside of the pedal opens access to the second

bank of presets. After pressing the ALT button, the small LED at the top of the pedal’s face will start

to blink, indicating that the second preset bank is accessible with the toggle switch. Upon moving the

toggle switch the center LED will turn red indicating the current preset is drawn from the second

bank.

Table of Contents Ultrawave Multiband Processor User Guide

Controls (Bass)

Note: The four top-level knob controls (Drive, Level, Mix, and Treble) can be reassigned in the Neuro

Mobile App and Neuro Desktop Editor from a list of many possible parameters.

The only main difference in Controls on the Ultrawave Bass is that a MIX knob replaces the SUSTAIN

knob on the guitar version. The MIX control is a dry to wet crossfade control. Fully clockwise on the

knob is full “wet”, meaning no clean signal is present, only signal distorted or manipulated by the

Ultrawave will be heard. At noon, there is a 50/50 clean mix, and at fully counterclockwise, the

signal is fully clean (no distortion).

Theory of Operation

A graphic or parametric EQ is a simple and common form of multiband processor. In that case, the

signal is split into separate frequency bands, levels in each band are set, and then the signal is

recombined. By controlling the levels in each band, a wide variety of tones can be created. The

Ultrawave takes this basic concept of multiband processing to a much higher level in the following

ways:

• applying varying levels and types of distortion.

• applying optional tremolo and phase offsets to each band.

• applying compression before or after the multiband processing.

Table of Contents Ultrawave Multiband Processor User Guide

• applying EQ where necessary to shape the tone.

• allowing for a complete set of alternate states to be defined in the multiband processor and

then “morph’ between both states via LFO), envelope, or expression.

• creating 2 complete signal paths with routing options for parallel processing, cascading,

placement of the effect in 2 locations of a pedal board, and the creation of complex stereo

images.

Simplified Multiband Distortion Example

The diagram above shows the Ultrawave in a classic multiband distortion application. Following a

gain/compression stage, the signal is then split into ten separate bands. Each band then passes

through dedicated and separate level setting and distortion stages. Finally, the ten bands are

summed together to form the output signal. There are many interesting consequences of passing

the signal though the ten bands rather than a traditional single band distortion stage. Firstly, the

distortion tone is significantly more harmonically complex. Secondly, it is possible to play complex

chords with more clarity. This occurs because each guitar string tends to find its own path through

one of the ten bands and is not “stepped on” by the harmonics of a neighboring string. The net

result is a distortion sound palette that is not found on the thousands of common distortion pedals

that are on the market.

Table of Contents Ultrawave Multiband Processor User Guide

Ultrawave Signal Path

The diagram above is a functional representation of the signal path inside the Ultrawave. One should

note there are 2 separate signal paths to provide true stereo, stereo imaging, and other multi-

channel routing options. The multiband separation, distortion, and gain control lies in the center on

the path. Note that the multiband blocks plus EQ and filtering can be “morphed” between two

defined states via LFO, envelope or expression. For instance, one could create a clear octave up tone

in one state and then a highly distorted foldback tone in the second state. If used with an envelope,

a struck note would ring with a clear octave up tone, but then decay into highly distorted foldback

fuzz. This is one example on an infinite range of possible sound creation options. There are two

compressors in the Ultrawave, and they can be placed before or after the multiband processing.

Through use of EQ and routing options, it is possible to use the Ultrawave as a 2-band compressor.

Finally, it is possible to add phase offset tremolo to each band. Multiband tremolo adds yet another

innovative and interesting option to the Ultrawave multiband toolbox. The diagram below

summarizes the function of each block.

Table of Contents Ultrawave Multiband Processor User Guide

Foldback Distortion

Foldback distortion is one of the many distortion curve options on the Ultrawave. It is worth some

background because they are not commonly found in effect pedals. In traditional distortion, as the

input signal voltage rises, the output voltage also rises, but begins to level off and finally pins (or

clips) at a maximum value. With a foldback curve, for large enough values of the input, the output

will begin to decrease. With more extreme amounts of foldback, after decreasing for a while, the

Table of Contents Ultrawave Multiband Processor User Guide

output can begin to increase again. Maximum foldback has many regions where the output

alternates between increasing and decreasing. These kinds of curves add a lot of high frequency

content to the output. It also can provide a lot of control over the sound, based on the level of the

input signal. With foldback, chords containing only octaves and fifths tend to sound best. Other

intervals can cause some strange, although not necessarily undesirable sounds.

Using a special shape of the distortion curve, strong second harmonics can be created, sounding like

a note an octave higher. Rolling off the guitar tone control or switching to the neck pickup will help

maximize the octave impression by attenuating the higher-order harmonics. Complex chords do not

typically work well for octave settings. The result is sensitive to the input signal level (as long as the

SUSTAIN and DRIVE controls are not set too high) and can give a sort of auto-wah effect.

A conventional distortion effect tends to turn the guitar signal into square waves. Playing harder

only makes the transition from negative clipping to positive clipping a little bit steeper. With the

foldback and octave algorithms found in the Ultrawave, a slightly higher input can have a radical

effect on the shape of the output signal.

Distortion Types

When using the Neuro Mobile App or Neuro Desktop Editor, you can select from a large list of

distortion types as you’re building a sound. Below is a guide to all the terms used in the Distortion

Type list, and how to differentiate between them. Essentially, the Ultrawave uses these sounds or

some combination of these sounds for each of the 44 distortion options.

For further reading and a visual representation of each unique distortion element, visit the Distortion

Appendix.

• Basic (Tube) Distortion - Similar to how Tubes feel and sound, gain goes from nearly linear to the

input signal, to sag, to compressed distortion based on input level.

• Hard Clip - like Op-Amp style hard clipping.

• Offset - like Asymmetrical clipping (for reference, a Boss SD-1 uses asymmetrical clipping compared

to a TS9 which uses symmetrical clipping in an otherwise similar circuit).

• Diode - Similar to LED Diode clipping.

• Gate - Any signal below the threshold is set to zero, and sustained signals will sputter out. Very

Velcro-like in nature.

• Absolute Value – Essentially, this is the “code equivalent” of the 2-transistor Superfuzz circuit that

causes an octave-up effect.

• Octave - Uses different tech for a smoother sounding octave, better for combining with other

elements like Foldback.

• Foldback - The classic, synth-like, overtone-rich effect from the original Multiwave. Derived from

modular synths. The distortion curve begins to collapse and turn back toward 0 when clipped.

Stereo Operation & Signal Routing

The Ultrawave is flexible for many different uses due to its stereo INPUT and OUTPUT jacks. By

default, the Ultrawave auto-detects the cables connected to INPUTS and OUTPUTS 1 & 2 and engages

the appropriate Routing Mode. Stereo Routing can also be performed manually with the Neuro

Editors; select between “Mono In, Stereo Out” or “Stereo In, Stereo Out.”

Auto Routing Modes

There are four routing modes available when the Ultrawave is in its default Auto Detect mode. See

detailed descriptions of each Auto Detect mode in the sections below.

• Mono In, Mono Out

• Mono In, Stereo Out

• Stereo In, Stereo Out

• Stereo In, Mono Out

Mono In, Mono Out

This is the most common use case. Plugging the incoming signal into INPUT 1 with OUTPUT 1

connected to an amp (or the next device in the signal chain) produces a standard mono signal. Dual

processing effects are also mixed down to a single output.

Mono In, Stereo Out

This is a very common use case that allows you to create some nice stereo imaging from a single

mono instrument input or use your Ultrawave as a splitter to send your signal to two separate

outputs. When the unit is bypassed in this mode, it will automatically switch to Soft Bypass mode to

maintain the bypass signal on the Channel 2 output. When Ch. 1 and Ch. 2 are linked, the processing

will be the same for both channels. When they are unlinked, you can configure separate settings for

Channel 2.

Table of Contents Ultrawave Multiband Processor User Guide

Stereo In, Stereo Out

This mode should be your default selection for Stereo In, Stereo Out applications. Stereo In, Stereo

Out allows you to continue your stereo chain of effects. When Ch. 1 and Ch. 2 are linked, the

processing will be the same for both channels. When they are unlinked, you can configure separate

settings for Channel 2.

Stereo In, Mono Out

This mode will accept stereo input on jacks INPUT 1 and 2. Inputs 1 and 2 are sent to Channel 1 and 2

respectively. When Ch. 1 and Ch. 2 are linked, the processing will be the same for both channels.

When they are unlinked, you can configure separate settings for Channel 2. The outputs of the

Channel 1 and Channel 2 equalizers are mixed together and sent to OUTPUT 1.

Table of Contents Ultrawave Multiband Processor User Guide

Additional Routing Modes

The Ultrawave supports two additional routing modes, Cascade Ch.1 -> Ch. 2 and Mono -> Stereo ->

Mono available in the Neuro Mobile App and the Neuro Desktop Editor. View the routing modes

below to find out how you can configure the Ultrawave’s inputs, outputs and dual channels using a

Neuro connection.

Cascade Ch. 1 -> Ch. 2

This routing mode allows you to run both channels in series, meaning Channel 1 will cascade into

Channel 2. This is a very useful routing mode in terms of tone shaping and drive-stacking. When Ch.

1 and Ch. 2 are linked, the processing will be the same for both channels. When they are unlinked,

you can configure separate parameters for Channel 2.

Table of Contents Ultrawave Multiband Processor User Guide

Mono -> Stereo -> Mono

This routing mode also allows for both channels to be run at once, but in this case, they are being run

in parallel. The Channel Balance control in the Neuro sound editor comes in handy in this routing

mode, as it controls the relative mix levels of each channel. When Ch. 1 and Ch. 2 are linked, the

processing will be the same for both channels. When they are unlinked, you can configure separate

parameters for Channel 2.

Preset Storage and Recall

User Presets store all user-editable parameters. This includes the knob positions, parameter settings,

frequencies, routing options, external control, and the full list of Neuro/MIDI-accessible parameters.

Included in every preset are settings for either channel (Channel 1 [Mono] or Channel 2). After a

preset is recalled, you can always tweak the top-level controls in a performance situation by turning

the knob. The knob parameter will then “jump” to the current knob position as it is rotated.

Recalling Presets

The first six User Presets are accessible via the onboard hardware or with an external footswitch in

the following ways:

1. Move the toggle switch to left, center, or right to access presets #1-3.

2. Press the ALT button, then while the Control LED is flashing, move the toggle switch to access

presets #4-6, or press + hold the footswitch when the pedal is OFF for 5 seconds (or 2 second in

“Quick Change” mode) to access the Red LED (presets #4-6).

Recalling MIDI Presets

All 128 available User Presets are accessible with an external MIDI controller. MIDI controllers can be

connected via USB port at the top of the pedal, or through a Neuro Hub, which connected to the

CONTROL INPUT at the top of the pedal. All 128 User Presets can be recalled with the corresponding

Table of Contents Ultrawave Multiband Processor User Guide

MIDI program change (PC) messages, or via continuous controller (CC) messages when accessing the

pedal’s internal presets via the Neuro Hub.

Note: When recalling presets via MIDI PC messages, you may wish to queue up your preset with

effect bypassed. To do this, simply engage the preset, bypass it with the footswitch, then re-save the

preset normally. When recalled, the pedal will load the saved user settings, but the effects will be

bypassed until you engage the pedal.

Copying a Preset to a New Location Using the Neuro App

Using the BURN and SAVE AS commands in Neuro Mobile or Desktop Editors, it is possible to copy

presets to any location in memory.

Clearing all Presets

All 128 User Presets can be erased using the Factory Reset procedure. Warning: The Factory Reset

procedure resets the entire pedal back to the state in which it was originally shipped – this includes

all global settings and User Presets. A Factory Reset will not erase any firmware updates.

External Control

Plug an expression pedal, an external footswitch, the Source Audio Tap Tempo Switch, or the Source

Audio Hot Hand 3 Universal Wireless Controller into the Ultrawave’s CONTROL INPUT jack and access

an array of external functionality and expression control.

External Switch

External switches can be used for several different control options. They provide an easy way to

remotely swap channels, tap the LFO tempo, and more. The Ultrawave is compatible with the Source

Audio Tap Tempo Switch.

External Switch Options

There are three main ways the Control Input port is utilized. Below are the possible used for the

Control Input port. Please note that External Switch Options is a global hardware setting.

Table of Contents Ultrawave Multiband Processor User Guide

Neuro Hub: This configures the Control Input port to receive MIDI code signals from the Neuro Hub,

allowing the pedal to be added to Hub Scenes (which are controlled by PC messages) and allowing for

MIDI CC (Continuous Controller) control.

Expression: Using the Source Audio Dual Expression pedal or a third-party expression pedal

connected to the Neuro Hub, it is possible to map up to three parameters to be controlled via

expression.

Tap Tempo: Connect a Source Audio Tap Tempo switch to be able to tap in the speed of the

Ultrawave’s LFO. The LFO can be set to control single tremolo, the multiband tremolo, morphing, or

a combination of those elements.

External Switches (1/8” TRRS Connection)

The Source Audio Tap Tempo footswitch can also be connected to the CONTROL IN jack using a

3.5mm (1/8 inch) cable. If you wish to use this function, you must enable the function globally with

the “Use Control Input for External Switch” option in the Hardware Options section of the Neuro

Desktop Editor.

Source Audio Tap Tempo footswitches can be purchased directly from the Reverb.com Official Source

Audio Online Store.

Expression Control

Use a Source Audio Dual Expression pedal to control up to three different parameters on the

Ultrawave per preset. Parameters include Drive level, Output Level, Treble, Bass, Mid Control, Noise

Gate Enable, and many more.

Connecting the Expression Pedal

Connect a Source Audio Dual Expression pedal using a 3.5mm TRRS cable from the EXP pedal’s

Sensor Output to the Ultrawave’s CONTROL INPUT port on the pedal’s top panel. Press the CONTROL

INPUT button to enable External Control.

If you are not getting the desired results from your expression pedal setup, go to the Hardware

Options section of the Neuro software. You’ll need to select “Neuro Hub/Expression” under “Control

Input Option”, and you may also need to calibrate your expression pedal. For more details, visit

Hardware Options.
